The Tánaiste and Minister for Health, Mary Harney, has said that people need to be more careful when driving.
She said recent deaths on the road were tragic, especially given that so many cases involved young people.
The Tánaiste said people had to take responsibility for their own driving and that a lot more needed to be done in this regard.
Earlier, the Chairman of the Road Safety Authority, Gay Byrne, again appealed to motorists to slow down following the deaths of 12 people in eight accidents since Sunday.
Speaking on RTÉ Radio, Mr Byrne said the gardaí had informed the authority that there were simply not enough officers to do what the public expect.
And he said measures were being put in place to make the roads safer.
In the latest incident, a 45-year-old man was killed while cycling on the Delvin road in Mullingar at 12.30am today.
He has been named as Patrick Gallagher of Cloughan, Co Westmeath.
Olivia Mitchell, Fine Gael Spokesperson on Transport, has said more resources are needed for gardaí, for speed cameras and administrative back-up.
A spokesperson for Minister for Transport Martin Cullen said the penalty points system would reduce the number of fatalities.
